One of the problems that can arise with the current LCD computer screens is that you may end up with one or more dead or frozen pixels, but to be able to find out if you have any you will have to resort to an application like IsMyLcdOK.
How IsMyLcdOK works is very simple, and it doesn't require any installation. All you have to do is open the program to be able to access the options that it provides to detect problems with LCD screens, with all the options being activated by means of the keyboard:
- Check the colors.
- Vertical and horizontal gradients.
- Horizontal and vertical lines.
- Paint lines and rectangles.
- Resistance test (that can be carried out with any of the prior options except paint lines and rectangles).
By means of these tests the user will be able to view the screen to see if there is any kind of problems, so as to be able to contact the manufacturer if there are.
Therefore, if you want to check the reliability and the functioning of your LCD screen, all you have to do is download IsMyLcdOK.
